Nec Spectraview 2180WG non-uniformity correction

If you have $6K to burn you can go out and buy a wide gamut Nec Spectraview 2180WG monitor and see all of Adobe RGB on your screen - but if you're a tech fetishist like me, with no money, then the Nec Spectraview 2180WG tech documentation will have to do, I guess.

One interesting interesting innovation incorporated in this monitor is the ColorComp 3d table (page 6) that mods individual pixels to compensate for display non-uniformity. My guess is the folded backlight system that mixes the LED light is not good enough at evening out illumination across the panel, and also some underperforming LEDs can always creep in to the production line, so it's smarter to try and improve matters with a "local profile". Nec would have you believe is that this is something they added out of the goodness of their hearts to compensate for uneven panels, as supplied.

I wonder how long it'll take until LED backlight panels come into general use.
